Jeffersonia dubia

Asian Twinleaf

Plant Type:

SHADE PERENNIALS

Jeffersonia dubia (ex: Ruth and Whitney Gorham) - Asian Twinleaf displays lovely open cup-shaped spring flowers in an alluring shade of light blue. Foliage arises dark red-purple and expands as the clustered flowers open. Foliage soon becomes green on wiry stems that may stretch as tall as 12 inches on some clones but often remains lower. As typical with this species the rounded peltate leaves last well into late summer, especially in more shade. Part, dappled to open shade in fertile, draining soil. Please be aware that once Jeffersonia dubia is settled into its home they resent disturbance. Pot grown division.

Genus Overview: Jeffersonia

Common Name: Twinleaf

Twinleaf. Each wiry stem supports a pair of mirrored kidney-shaped leaves. The ephemeral flowers in April-May are cupped daisies in a light pink to white tint. They are followed by pear-shaped seed pods that suddenly pop open spewing forth the small seed. The dried seed pods look like little stylized Jack-in-the-pulpits and can be used in small autumn/winter dried arrangements. Though not found in New England it is hardy for us in the southern reaches of the Northeast. Named for Thomas Jefferson, this most handsome member of the Berberidaceae looks great all season in the woodland garden. Site them in draining soil in dappled to open shade conditions. The following are offered by division. We’re likely to only have but a few available annually as they resent disturbance and are then very slow to size up. Be certain to check availability numbers before ordering. Only one per customer and please order early.
